While loops

  // While loop may never end can crash you computer
  let n = "10";
  n = Number.parseInt(n)

  let i = 0;
  while (i<n) {
      console.log(i);
      i++;
  }

  // do while loop runs atleast once , code runs first and condition checked second
  let i = 5
  do {
      console.log(i);
      i++;

  } while (i < 20)
